On March 5th, professor Andrea Bertozzi gave a talk entitled “Tears of wine and shock dynamics” at the 2019 annual physics conference hosted by the American Physical Society. Bertozzi and her team revisit the classical problem of "tears of wine" and enhance the existing theory. The new theory reveals missing dynamics in this problem which involves non-classical shocks.Other UCLA researchers working on this project include Ph.D. student and NSF graduate fellow Yonatan Dukler and assistant adjunct professors Claudia Falcon and Hangjie Ji. Their research has been featured in various publications including ARS Technica and Food and Wine.
